HENRY A. CONSTANTINE, F NIAGARA FALLS, NEW YORK.

WET- ACHINE.

i To all whom it may concern:

Be it known thatl, \HEN'RY'A. CONSTAN- TINE, residing at Niagara Falls,in the county of Niagara and State of New York, have invented certainnew, and useful 11nprovements in Wet-Machines, of which the following isa specification. V

This invention relates to improvements in wet machines, and an objectthereof is to provide means for automatically removing the sheets offiber which are accumulated upon the pressure roll. i V

A more detailed object is to'provide means which will bring about adischarge of the sheets of. fiber at regular intervals during theoperation of the machine, so that said sheets will be of uniform weightand texture;

A more detailed object is to provide means associated with the mentionedpressure roll,

preferably adapted to rotate therewith, and constituting a cutter whichwill be operated to cut longitudinally through the circular band offiber which has accumulated upon the pressure roll, so that one end ofsaid band will fall by'gravit'y from theroll and thereby facilitate theautomatic discharge ofthe remainder of the band as a'sheetas the rollcontinues to' rotate.

Other objects and'aims of the invention, more or less specific thanthose referred to above, will be in part obvious and inpart pointed outinthe course;v of the following description of the elements,combinations, arrangements of parts and applications of principles,constituting the invention; and the scopeof protection contemplated willbe indicated in the appended claims.

In'the accompanying drawings Iwhichare to be taken as apart of thisspecification, and in which I have shown a merely preferredform ofembodiment of the invention Figure 1 is a diagrammatic view illustratingawet. machine with the improve ments of this invention incorporatedtherein.

Fig. 2 is a front elevational view ofthe pressure rolls, illustratingtheir supports and portion of one'of said rolls being broken away tobetter disclose the elements consti tuting this invention;

Fig. 3 is an enlarged fdetailedend view of the end of the pressurerolls, illustrating the relation of the elements constituting thisinvention with the pressure rolls, 7 i

Fig. 4c is a view simila'rto that shown in Fig. 3, but theparts arebeing illustrated'in a different position.

Fig. is a fragmentary detailed View illustratmg the manner in which 'thefiber is cut, and i v i "Fig. 6"1s an enlarged fragmentary deadjustmentof the cutter. I v Referring to the drawings for a detailed descriptionof the structure illustrated; therein, the reference character Lindicates the-frame of the machine, the reference tailed v1ew,llustratmg a means for effecting V character G indicates the upperpressure roll, and thereference character H indicates rolls and receivesface iof the belt at its upper side. As the,

fiber which is deposited upon the outer surface of the belt movesbetween the rolls G and H, it ispicked up bythe roll. G and forms a thinlayer upon said roll.' rotation of the'roll causes athicklayer offiber'tc be accumulated thereon, as illus, trated at 4E in Figs'is ands.When this layer be removed from the'roll to make roo'mffor a repetitionofthe operation All of the above is in accordance with the well knownoperationof machines of this type, and 'here' toforev it operatorstationed to slit ,the' accumulated roll or band 4 lengthwise withahandknife whenever he deemed the time proper, sothat' a portion of theband at 'one side of the -Rejpeated 1 reaches the required thickness, itmust has been, the custom to have an slit will fall downwardly andpermit the remainder of'the band to be discharged as a sheet by thecontinued rotationof the'roll. This has resulted in sheets which are notonly out along crooked or uneven lines, but

5 and 6 i are fixed one which are also of greatly varying'thi'ck- 7 atregular intervals and of uniform thick- V Y leave fingers 1O projectinga short distance beyond the pivots. The opposite ends of the a cuttermember 11.

erably formed of small diameter piano wire. Where heavier wire or adifierent typeof cutter is employed, or even. where the, small diameterwire is employed, the same may be let into a groove in. the roll, sothat its cutting edge will lie flu'sh'with orbelow the adjacent surfaceportion of'the roll. vVhere wire is used, a suitable take-up device, asindicated at 12, as shown in Fig. 6 is employed. j

The plate 5 extends so as to constitute a positive support for the longends of the levers 7 and 8 to receive the strain applied to said leversby the tension of'the wire. The levers are preferably bent intermediatethe ends of the long arms thereof so as to maintain a substantialcontact with the .surfaces of the plates even during pivotal movement ofsaid arms.

.An operating bar 13 is arranged beneath the roll G, substantially asindicated, said bar being mounted to slide longitudinally withinsuitable bearings 14 formed in the frame or supports L. A tensionspring15 is provided for urging the operating bar in a direction toward theright in Fig. 2. .A pin or roller 16 is arranged at the left hand end ofthe bar adapted to engage against'the outersurface of a cam wheel 17which is rotatably mounted upon the adjacent support L. Movementof thebar toward the right is resisted by engagement of the pin with the faceof the cam.

A lug or pawl 18 is provided-upon the plate 5 disposed to engagesuitable ratchet pins or teeth 19 upon the-cam wheell'Lso as to causethe-cam Wheel to rotate the space of one'tooth at each completerotation; of the roll Gr There may be as many teeth or pins 19 asdesired for determining thenumber of rotations which will be completedby the roll G for each rotation of. the cam. In fact,

the number of teeth may be readily altered at'any time, particularlywhere pins are employed as teeth, by simply insertingorremoving one ormore pins according to requirements. Obviously'other means thanremovable pins maybe employed for accomplishing the same result.

The outer face of the cam 17 is formed with a depression 20 at one pointof the periphery thereof adapted to receive thepin l6.upon' thecompletion of each rotation of theca'm. When pin 16 falls intothe depression 20, the operating bar moves to the right, a distance equal to the.depth of the depression and disposes a pair of stop-shoulders 21 and '22in the path. of movement of the finger 1.0, so that asroll G revolves,the fingers 10 of the levers 7 and 8 come into The stop-shoulders 21 and22 are preferably adjustably connected to the operating bar, and-for thepurpose of this adjustment said shoulders are illustrated as comprisingseparately formed members connected by screws or bolts 23, which extend.through slots 24 formed. in said members. The shoulders may thus beadjusted to accommodate themselves to slightinaccuracies of. adjustmentof the other. parts, or to take up wear, or for other purposes. 7

It will of course be understood thatthe operating .bar and, thestop-shoulders are arranged insuch relation. to the roll and the partscarried therebythat they will operate tocause the cutter tomove tocutting position at a time when the cutter is in. themostappropriateposition to facilitate the proper andspeedy discharge ofthe fiber sheet from the roll. This position is clearly indicated'inFig. 4, wherein itwill be seen that the portion of the fiber below thecutter is free to fall by gravity away from the roll, so that ,as theroll continues to revolve, the fiber .will be discharged from between Ithe two rolls as asheet in the. usual manner.

It .will be further noted that the movement. of the cutter outwardlyaway from the roll assists in freeing-the fiber from the roll by givinga certainbutward thrust thereto. It will also be,noted,.especially wherea wire-cutter is employed, thatthe fiexibil ity of the wire, and thefact that it issupported only by its opposite ends, .will causethecutting action to begin at the opposite I edges of the sheet of fiberand;to travel gradually inwardly from said opposite edges toward themiddle of the fiberdueto the natural bowingof the. cutter which willfollow. A shearing action is thus afiorded which insures a cleanandrapid cut.

As many. changes couldbe made inthis construction without departing fromthe scope of the i 'ollo wingv claims, it isintended that all mattercontained in the above description, or shown in the accompanyingdrawings, shall be interpreted as illustrative only and not in alimitingsense. 7

Having thus described my inventionwhat I claim asnew and desire tosecureby Letters Patent is: :7 i 1 v 1. In a wet machine of the usual typecomprising a roll adapted 'to-accumulatea deposit thereon, a flexiblecutter carriedgby said roll, and meansfor operating said cutter tofacilitate discharge ,of the deposit from said roll in the usual manner.
